Effect Of Tannins Extraction On Activity Of some Pathogenic Bacteria .

Abstract

This study investigate the effect of extraction for each of (Quercus Infictoria , Punica granatum L. fruit cortex , Klebsiella pneumonia & Tanic acid .) on the activity of four positive & negative pathogenic isolates for Gram stain , the include ( Escherichia coli , Klebsiella preumonia , Proteus mirabilis& Staphylococcus aureus ) using well – diffusion agar , isolates were taken from the microbiological Department of laboratory in Kirkuk general hospital , the extracts gave greater inhibition activity against the whole four bacteria isolates , the Escherichia coli bacteria were more susceptible from other bacteria type , Punica granatum L. fruit cortex extraction also showen more activity to discouragement bacteria than other extraction type .
